1 Claim.

My invention pertains to a support peculiarly adapted for the support of an electric heater to be used in the industrial arts, more generally in the application of a heating and/or drying effect by reflection in a downward direction upon miscellaneous materials before or after becoming otherwise conditioned upon a machine.

One object has been the provision of a multiple adjustment in order to accommodate itself to the style of machine in conjunction with which it is to be used, which is to say, so that a suspended heater assumes the proper elevation, a suited crosswise position and a chosen angularly related presentation, as determined by the shape and size of the machine (for instance, a printing press) the material conveyed on the machine and the measure of heat required to condition the material along its path of travel. Another object has been to provide a standard mounted on a roller carriage to facilitate a shifting of its position bodily toward or away from the machine, together with either wheel-brake casters of a frictional base and mechanism for effecting relative movement between said carriage and base whereby either the carriage rollers or the base are caused to engage the floor. Other objects have been compactness, sturdiness, durability, ready detachment of certain parts and economy of manufacture.

Adverting t the sheet of drawings Figure 1 is an elevation of a heater support embodying my invention, and ShOWll'lg in dotted lines three, alternate positions to which the supported heater may be adiustably shifted.

Figure 2 is a top plan view, but showing, in dot and dash, two additional adjustments which may be accomplished.

A carriage 1 includes one arm carrying at each of its two ends an ordinary caster 2 and a relatively transverse arm supported at each end by a marketed type of wheel-brake caster 3 which additionally comprises a brake setting lever 4 and a brake releasing lever 5, whereby the rolling of the carriage may be controlled.

No claim being made to the carriage with its functionating (braking) control, there need be no further description except for this mention that it is intended freely to roll it along with herein, subsequentin described superstructure to a point on the shop floor adequately close to where the heated zone is to be created preparatory to accomplishing the frictional resistance to its bodily displacement.

An upright tube 6 is secured in any feasible manner to the carriage and near its top is provided with an operatively connected set screw l adapted to abut the telescopically enclosed tube 8 and to fix it in an innumerable number of vertically slidable positions. The upper end of the tube 8 is provided with a right angularly related arm 9 and also provided is a collar 58 which loosely encircles the tube 8, which is somewhat larger in diameter than the tube 6 and which may be similarly fixed to the tube 8 by means of a set screw ll. The purpose of the adjustable collar H! is to maintain any established elevation of the arm 9 after the set screw 1 has been loosened to permit a turning movement of the tube 8, for instance, through that number of degrees Which will cause the arm 9 to assume the position in which it appears in dash and dot in Figure 2.

An electric cord l2, for connection below with a source of current, passes through an eye or clamp is projecting from the carriage, thence through an eye or clam-p M near the top of the tube 6 and likewise through an eye or, if preferred, through a clamp l5 at the junction of the tube 8 with its arm 9. The cord is to lead to electrical resistance units within the confines of a concavo-convex reflector l6, but not claimed in this application. An end wall of the reflector carries a hollow boss I! in which the tubular arm 9 is slidable subject to the engagement with a set screw l8.

Telescopically fitted in turn within the arm 9 is a rod I!) which passes through a similar hollow boss 20 on the other end wall of the reflector and in axial alinement with the boss H. A set screw 2| is adapted for adjustment through the boss 20 for alternatively binding or releasing the rod 59. The extremity of the latter is intersected by a cotter pin 22 to prevent separation of the rod and reflector.

It should be evident that a vertical adjustment, indicated by the row of positions of the reflector I6 in Figure 1, is had; that a horizontal adjustment, indicated by the leftward shifted intermediary position of the reflector iii in Figure l,

is had and that not only may. the arm 9 be swung around in a horizontal plane, but the reflector may be turned about the common axis of the bosses H and 26, as indicated by the disclosure in its dot and dash position in Figure 2 preparatory to being so held by either one of the set screws l8 or 2 i. In addition to the adjustment of the entire structure upon release of the brakecasters, there is provided a vertical and a horizontal straight-line adjustment and two swinging adjustments about relatively transverse axes. In

prising a pair of telescopically connected meme bers permitting adjustment of said arm 7. 3 3 and also about a vertical axis.
